    摘要: A high frequency signal, which is produced in a oscillator (2), is modulated by a frequency from a modulating signal generated by a modulation signal generator (1) and radiated from a sending antenna (5). A reflected signal from a target object is received by a receiving antenna (6), and frequency-converted by a local oscillating signal from a directional coupler (4) in the frequency convertor. Then, distance and speed information is detected by a signal processing unit (8). A modulator (3), which is connected to the oscillator (2), modulates the oscillator output in order to detect a failure. A detection unit, in which a filter unit (10), a rectification circuit (11), and a voltage comparison circuit (12) are included, detects modulated elements originated in the above described modulator. The signal processing unit makes a failure determination based on the modulated elements which have already been detected.

    摘要: In an FM-CW radar system, a frequency modulating wave output from said modulating signal generator has a frequency variation skew with respect to a time axis (modulation skew), and the radar system includes a means for varying the modulation skew by controlling the modulation frequency amplitude or modulation period of the modulating signal. The radar system further includes a means for discriminating a signal component varying in response to the variation of the modulation skew, thereby discriminating a signal related to a target object from other signals. In the case of an FM-CW radar system that performs transmission and/or reception by time division ON-OFF control, the radar system includes a means for discriminating a signal which, when the frequency used to perform the ON-OFF control is varied, varies in response to the variation of the frequency, thereby discriminating a signal related to a target object from other signals.

    摘要: In a radar apparatus, a receiving antenna (12) includes a plurality of antenna elements (12 1 , 12 2 , ...), each receiving, as a reception signal, radio waves emitted into space and reflected off a target object. An analog signal is obtained by downconverting and putting a bandwidth constraint on the reception signal, and is then converted to a digital signal. Based on the digital signal, a signal processing unit (20) detects the bearing of the target object. The signal processing unit (20) performs processing based on outputs of two sets of the antenna elements(12 1 , 12 2 , ...).
